340 cam advice

I hear everyone out and agree with the need for gearing and stall. I've been around modded cars enough. My definition of 95% street is very loosely used. I would not drive this thing in the hwy likely and I could care less about mileage. I guess I just wanted the best of both worlds LOL. I agree 3.91's ain't bad and I will likely go with the higher stall. I am also considering a Comp Cams X275HL cam. specs are duration 235 @50 and lift .525 with a 110 LSA, 106 CL
